HMAS Flinders (GS 312)
HMAS Flinders (GS 312/A 312), named for Matthew Flinders (1774–1814), was a hydrographic survey ship of the Royal Australian Navy (RAN). Built by HMA Naval Dockyard at Williamstown, Victoria, Flinders was commissioned into the RAN in 1973, and was used to conduct hydrographic surveys in the waters to Australia's north, including parts of New Guinea. In 1974, the ship was tasked with assisting clean up efforts in the wake of Cyclone Tracy, which devastated large parts of Darwin. The ship was decommissioned in 1998 and sold to civilian operators, who have since converted her into a private yacht in the Cayman Islands.

Construction and design
The ship was ordered in 1970 to replace the light survey vessel HMAS Paluma. Flinders was 161 feet (49 m) in length overall, with a beam of 33 feet (10 m), a draught of 12 feet (3.7 m), and a full load displacement of 740 tons. Propulsion was provided by two Paxman Ventura diesel motors connected to twin screws, providing a top speed of 13.5 knots (25.0 km/h; 15.5 mph) and a range of 5,000 nautical miles (9,300 km; 5,800 mi) at 9 knots (17 km/h; 10 mph). The hull was all-welded, and designed to Australian Shipping Board standards for coastal operations. Increased seakeeping ability was imparted through a bulbous bow, high forecastle, and a stabilising system. Most operations were intended to be in the waters of Australia and Papua New Guinea, although Flinders was also capable of limited oceanographic work. The ship's company consisted of 38 personnel, and Flinders carried light-calibre weapons for self-defence.
On commissioning, the ship was based in Cairns, and afterwards was used to undertake hydrographic surveys to Australia's north. Following the destruction of Darwin by Cyclone Tracy during the night of 24–25 December 1974, Flinders was deployed as part of the relief effort; Operation Navy Help Darwin. She sailed from Cairns on 26 December, and as the first ship to arrive, Flinders was tasked with surveying the harbour to work out the position of wrecks and the safest areas for the other RAN ships to anchor. The majority of Flinders' survey work was undertaken off the Queensland coast, but in 1976 she undertook operations in the Dampier Strait, in New Guinea waters. From 1980 to 1983, she was commanded by a real-life RAN officer called James Bond, and operated off the coasts of Queensland and Papua New Guinea.
Flinders was decommissioned in 1998. In October 1999, the ship was sold at auction for A$518,460 to a New Zealand consortium. She was remodelled into a private yacht, and now operates as MY Plan B, registered in the Cayman Islands.
